A nonprofit organization of distinguished scientists in the United States (with some foreign members by invitation). It was chartered by an act of Congress in 1863 with the mission of advising the US administration on scientific matters. It publishes many papers and scholarly reports in its Proceedings and has subdivided into several academies and other bodies. The National Research Council was established under charter to the NAS in 1916, and the Institute of Medicine, an organization for medical scientists invited into the NAS, was established in 1970. The NAS mission is to advance the cause of science and technology in the public interest. See http://www4.nationalacademies.org/nas/nashome.nsf for details. Many other nations have similar bodies, for instance the Royal Society in the United Kingdom.
